Not so fast
By Mike on 09/14/2019
Used recommended amount, 1/2 teaspoon. It took 7 days to start to notice the crabgrass turning white. Checked weeds along side of house yesterday, finally dying. tomorrow is 3 wks, ready for 2nd application. Put the right amount of dye in the 1 gal. sprayer and could hardly see it. I believe it took longer to act than what was written on the instructions. Hopefully it works better in the spring as a preemergent, or it's not worth the money.

Tenacity is almost perfect
By Ryan on 09/27/2019
Works amazingly on crab grass and clover. Has not been as effective on the broad leaf plantain and creepy Jenny. Two applications late summer and an early Fall over-seed has taken back control of the lawn. Will have to see how the lawn responds when I get a pre-emergent application down in the spring.

Tenacity works!

Extremely effective.
By Jon on 10/04/2019
The ability to use as a pre- or post-emergent is incredibly useful. The effectiveness on such a broad spectrum of weeds allows fewer applications of herbicides which is always a plus. It had a short lived whitening affect on some of my newer fescue cultivars, but they popped back to green with regular watering in a few weeks. This is definitely my first choice moving forward.

So far, so good.
By Nrobertson on 10/04/2019
So far so good. Our yard has been infiltrated with crab, clover and who knows what else type of weeds. First application was applied and I anxiously waited to see what would happen, but realized I needed to be more patient as you do not see immediate results. Approximately 5 days later, there it was...the beginnings of discolored and death of my weeds! I couldn't wait for the second application, which I applied 2 weeks later. Tenacity might be more time consuming than one might expect, but overall I feel quite confident that my lawn will soon be back to the green luscious lawn that we once had.
Happy lawn

Mixed the three solutions sprayed on lawn as per instructions and it took about a week to activate and suddenly all the clover crab grass and dandelion's started turning white. Good bye nasty weeds! This is a great find my neighbors will all be ordering soon thank you again. I have tried many other chemicals to get ride of clover nothing worked I would never use the nasty toxic stuff from Monsanto, this is the safest solution I could find.

Perfect Solution for my Lawn
By Rae on 04/03/2020
Chat team was super helpful in advising me on products/seeding combo. Applied Tenacity 2 weeks ago. It took 7 days to see any changes, but getting ready to re-apply as per instructed and so happy with the results. The clover that has been lingering for years is gone!...the weeds too. Thanks!

It's working!
By Janet on 04/17/2020
After trying for 5 years to control the weeds in my yard, this product appears to be the first that's really working. The weather hasn't been cooperating, so I haven't had a chance to use it on my entire yard, but in the areas where I've sprayed this, the weeds have turned white and then disappeared. Great product AND great service from the provider. Thanks!
Tenacity Herbicide
By Matt on 04/17/2020
This stuff is legit. Had some extremely stubborn crab grass and it knocked it out like a dream. Followed the directions and it worked great. Killed all the other weeds as well. Used some blue dye to mark the areas I sprayed and it was a big help. Applied it three weeks ago and the crab grass is non existent. Excellent product.
Still not sure if it'll kill my Crabgrass.
By Ed on 04/17/2020
Almost 2 weeks now and some slight discoloration of the crabgrass stalks. Some heavy duty stuff at 1 tsp per gallon of water. Using on centipede and very hopeful for success. Instructions say it'll kill post emergent poanna as well. I haven't tried that yet, waiting on Summer heat to kill it and then use pre emergent next year.
Works OK on Some

2 weeks in
By Blaine on 04/17/2020
I almost went with 5 stars but I just dont know enough yet. It will be 2 weeks tomorrow from the first time that I used Tenacity. After 1 week, my crabgrass began turning white. I just noticed yesterday that the clover weeds had begun turning white. I have some other weeds in my grass (not sure what they are) but i don't think I've noticed them turning white yet. This is only my first application and I used dish soap as a surfactant. I am thinking about investing in a true surfactant for my second application next week, we will see how it goes.
Small bottle BIG RESULTS
By Gigi on 04/21/2020
Recently I decided to over seed my old beat up and tired lawn. Before I bought my seed I went ahead and applied a blanket treatment of tenacity only a pre-emergent with no surfractant. During the time of application I did notice weeds growing due to it being early spring in the Midwest, but that was not of my concern. My plan of attack was to overseed to punch out all the crabgrass and wild weeds. As I was prepping the lawn for the seeding two weeks later to my astonishment and to my surprise I noticed all my crab grass and wild weeds were all white and dead. Pretty much all of it was killed with out a surfactant. My main purpose was to use it as a pre-emergent but it actually works as a post to merge it with out surfractant

Slow acting but works
By Carmen on 04/24/2020
Bought to help control and identify poa triv. After spraying results took about 2 weeks to appear. Product is working and has not harmed turf. Also plan to use when seeding. Lawn is cool season tttf for reference. Do my own was awesome as always and product arrived quickly even with the current situation. Thanks.
Mediocre at best
By James on 05/02/2020
I really wanted to like this product, but after my second year of using it I find it to be mediocre. I have followed the directions exactly including using surfactant, and my experience is that 1) it partially kills off some weeds, but leaves others unscathed (it's totally ineffective against clover), and 2) it takes forever. Do you like to wait six weeks for a weed to die? I don't. My dandelions are dying off, but the product works so slowly that they have had time to flower and seed. My lawn has the same or more weeds after two seasons on Tenacity than it did in the past using cheap and fast Weed-B-Gon.
